One of our papers looked at the influence of the decolourization approach that is used in an SfM algorithm to convert the input colour imagery to greyscale:

DOI: 10.1007/978-3-319-01784-6_3: a book chapter which focuses on several types of archaeological airborne frame images, the distortion factors that are influencing these still images and the necessary steps to compute orthophotographs from them. Rather than detailing the conventional photogrammetric orthorectification workflows, this chapter mainly centres on the use of a SfM+MVS workflow. In addition to a theoretical underpinning of the working principles and algorithmic steps included in both SfM and MVS, real-world imagery originating from traditional and more advanced airborne imaging platforms is used to illustrate the possibilities of such a computer vision-based approach.
